Definitions

  • the invention relates to a dispenser for dispensing metered quantities of liquid to pasty products, consisting of a cylindrical bottom open storage container whose lower open end is closed by an axially displaceable piston and a dispenser head arranged on the storage container, which contains a bell-shaped dispenser pump with elastic side walls, which together with the top surface of the storage container and its inlet valve and an outlet valve arranged in the pump neck forms a closed pumping chamber, wherein the outlet valve is made as part of the pump neck with this so in one piece that closes the entire upper through hole of the pump neck with a valve flap by a simple operation is, which rests in the initial position sealing on the pump neck.
  • a dispenser of the type described above is known from EP 0 048 420 B1 known.
  • the dispenser consists of a hollow cylindrical storage container with a lower open end, which is closed by an axially displaceable Nachkolbenkolben.
  • the upper end of the storage container has a top surface with an inlet valve.
  • a dispenser head is arranged with a dispenser head located in the dispenser pump, the pumping chamber input and output side is limited by check valves and is formed with a downstream of the dispenser pump mouthpiece with application opening.
  • the discharge valve Upon release and subsequent release and expansion of the donor pump, the discharge valve is closed and the input valve is opened.
  • the vacuum formed by the expansion of the dispenser pump in the pumping chamber now causes a suction of new product from the storage container through the inlet valve of the top surface, at the same time the Nachschreibkolben or closure moves further towards the top surface. This process can be repeated until the storage container is empty and the Nachschreibkolben has contact with the top surface.
  • the outlet valve is designed as a flapper check valve and has a concave, pivotally connected to the end of the pump neck valve flap, which rests in the closed position dome-shaped on the vertically arranged pump neck.
  • the arranged in the top surface of the container inlet valve consists, as the same applicant in the US 4,394,939 is made closer to this donor, from a circular symmetrical in the top surface with an angle ⁇ (45 ° to 85 °) from the radially extending to the container axis plane, with distance from the container axis extending annular slot as a valve opening, whose surface is the shape of a in Direction of the pump room widening truncated pyramid or funnel has.
  • the valve flap used here is a sealing ring formed with a circular cover ring, which is held on at least three, leading to an axially with respect to the container on the top surface to be fastened hub spokes.
  • the cover ring which is adapted to the inclined position of the annular slot, sealingly abuts only with its sealing lips on the annular slot.
  • a toothpaste dispenser with pump known, consisting of a pump part and a reservoir, which are bolted together.
  • the pump part is formed below with a comparison with the reservoir final, containing valve holes partition.
  • the inlet valve of the pump part is a valve disc which is fastened centrally above the valve bores on the dividing wall and alternately opens and closes the valve bores in accordance with the pump cycles that have been carried out.
  • An exhaust valve does not have the pump part.
  • dispensers are usually no longer refilled after their emptying, but disposed of.
  • the most economical and simple manufacture of the disposable product "dispenser" is of particular importance, in particular for the more complicated construction parts contained in the dispenser, such as, for example, the check valves, whose valve flaps are subjected to mechanical stress and faultless throughout the entire process
  • the check valves are often in hard to reach areas of the dispenser, whereby the attachment of usually riveted valve flaps can often be difficult and costly.
  • a dispenser of the type mentioned above with the characterizing features of claim 1, characterized in that the passage openings of the inlet valve and the exhaust valve closing valve flaps are formed similar and each of a flat elastic disc with a central hole, which are mounted on a protruding axial mandrel of the top surface of the storage container or on a protruding axial mandrel of the pump neck and secured there, and lie in the starting position in a plane sealingly on the through holes of the valves.
  • the bell-shaped as an integral construction element dispenser pump of the dispenser head which is inserted from below into the dispenser head and in the mounted state (on the storage container, the dispenser head is attached) together with the top surface of the storage container forms a pumping chamber is at its upper end to a neck narrowed with circular cross-section.
  • This inside hollow neck of the dispenser pump represents the outlet opening of the pumping chamber and is used by placing a valve flap on its upper end as an outlet valve.
  • the projecting axial mandrel of the pump neck is part of the donor pump or the pump neck and is made in one piece with this, wherein it is connected via webs with the pump neck.
  • the elastic disc such as a rubber disc
  • this is formed with a circumferential groove at the level of the upper edge of the pump neck into which engages the rubber disc when plugging.
  • the rubber disc In the dispensing operation, with the discharge valve open to discharge the product, the rubber disc is cambered with its outer periphery up toward the mouthpiece while the center of the rubber disc remains in its original position through the circumferential groove of the spike. Upon return of the exhaust valve by the negative pressure generated in the pumping chamber, the outer edge returns to its original position and the rubber disc reseals sealingly on the pump neck.
  • the pump neck is made in one piece with a closed cap closing off the top of the neck.
  • this cap is then only partially separated from the pump neck so that the cap remains connected to the pump neck over a remaining unseparated area in the form of a tab. Since the tab is made of the same elastic material as the entire donor pump, the tab now acts as a hinge for the valve flap, the original cap of the pump neck.
  • valve flap is thus reduced to a simple partial separation process on the one-piece by, for example, injection-molded dispenser pump.
  • FIGS. 1-3 showing a dispenser according to the invention.
  • Figures 1 and 2 is in a vertical section (Fig. 1) and in a front view 2 shows a dispenser 1 for dispensing metered quantities of liquid to pasty products with a dispenser pump 10 designed according to the invention.
  • the dispenser 1 consists of a storage container 3 with a lower open end 31 for filling the product to be dispensed. After filling, this open end 31 is then closed by a Nachschkolben 32.
  • the upper end of the storage container 3 is bounded by a cover surface 30 with inlet valve 7.
  • the dispenser head 2 On the storage container 3, the dispenser head 2 is pushed, consisting of the bell-shaped or dome-shaped dispenser pump 10 with an outlet 8 and with a discharge valve 8 downstream dispensing channel 6, mouthpiece 4 with application opening and locking tab 5.
  • the dispenser head 2 is so on the storage container 3 postponed that the bottom open dispenser pump 10 is seated tightly on the top surface of the storage container 3 and is locked with this and between the dispenser pump 10 and the top surface 30, a pumping chamber 18 is formed.
  • a cap 9 On the dispenser head 2, a cap 9 is pushed to protect it.
  • valve flap 20 is formed for example by a rubber disc with a central hole 26, which is pushed onto a central mandrel 11 of the pump neck 12.
  • the dispenser pump 10 of Figure 1 is shown enlarged again.
  • the mandrel 11 has at the level of the upper edge 27 pump neck 12 a circumferential groove 14.
  • the valve flap or here a rubber disc 20 is pushed with its central hole 26, wherein it engages in the groove 14 and sealingly rests on the upper edge 27 and thus the entire upper through hole 15 of the pump neck 12 is covered.
  • FIG. 4 shows a different design of an outlet valve 8.
  • the pump neck 12 is changed in this alternative embodiment.
  • the upper end of the pump neck 12 is smooth and formed with a pivotable valve flap or cap 20 '.
  • the pump neck 12 and the cap 20 ' were made in one piece and then partially separated by a separation process so that the cap 20' is only movably connected to the pump neck 12 via a small unseparated area, a tab 22.
  • the thus movable cap 20 'or valve flap thus represents a particularly simple embodiment of a valve flap, the functionally reliable the pump neck 12 and the passage opening 15' sealingly closes and opens.
  • FIGS. 5 and 6 a dispenser head 2 of a dispenser 1 with a dispenser pump 10 is shown in an enlarged partial section, the outlet valve 8 of which, according to FIG. 4, is not formed with a flat but with a dome-shaped valve flap 20 "which together with the Pump neck 12 was made.
